Abstract:Abstract: Objective To investigate the value of Oxycodone in prevention of Fentanyl-induced cough. Methods In this study, 186 patients undergoing elective surgery under general anesthesia in our hospital from January 2013 to November 2015 were enrolled and randomly divided into Oxycodone group, Dexmedetomidine group and control group, each group had 62 cases. The patients in the Oxycodone group were given Oxycodone 0.1 mg/kg by intravenous injection; the patients in the Dexmedetomidine group were given Dexmedetomidine 1 μg/kg by intravenous injection; and the patients in the control group were given normal saline 10 ml by intravenous injection. In 5 min after that, all the cases were given Fentanyl 3 μg/kg by intravenous injection within 3-5 s, 2 min after they were given other anesthesia induction drugs. The preoperative baseline data and incidence of cough were compared among the three groups. Results There were no significant differences in the preoperative baseline data among the 3 groups (P > 0.05), so they had comparability. The incidence of cough response in the Oxycodone group, the Dexmedetomidine group and the control group was 3.2% (2/62), 12.9% (8/62) and 27.4% (17/62) respectively, there were statistically significant differences among them (P < 0.05), and the incidence in the Oxycodone group was significantly lower than that in the Dexmedetomidine group and the control group (P < 0.05). The cough response in the Oxycodone group and the Dexmedetomidine group was significantly milder than that in the control group (P < 0.05), and there was no significant difference between the Oxycodone group and the Dexmedetomidine group (P > 0.05). Conclusions Intravenous injection of Oxycodone 0.1 mg/kg could significantly reduce the incidence and severity of Fentanyl-induced cough, and its preventive effect is better than that of Dexmedetomidine. It is worthy of clinical popularization and application.
